How can men maintain their youth through proper care?

　　1. Common razor, five and a half years younger.

　　A study by Northumbria University in the UK found that men who shave appear 5.5 years younger than men with stubble. Skin Expert Dr. Kenneth Bell stated that shaving stimulates the production of collagen in the face, resulting in smoother skin.

　　2. Eat less, remember more.

　　German researchers have found that reducing calorie intake can help decrease the likelihood of inflammation, which can lead to a decline in cognitive abilities. Scientists say it's best to reduce daily calorie intake by 30%, so if you originally consumed 2,500 calories a day, you should cut down by 750 calories.

　　3. Get enough sleep, and your face will stay young.

　　Long-term sleep deprivation accelerates facial aging because the muscles around the eyes can be exercised during rapid eye movement in sleep exercise , and if you don't get enough sleep, the muscles around the eyes will atrophy, leaving dark circles under the eyes.

　　4. Exercise regularly, stay 10 years younger.

　　A new study published in the U.S. Archives of Internal Medicine shows that engaging in three hours of moderate-intensity exercise per week can make a person feel 10 years younger physically.
